Major General Nawaz rejected the claims that the Taliban were operating from Quetta, calling the reports as "baseless."
Replying to a question, he said, Mullah Omar is not in Quetta and western media and leaders despite having technology often make false claims in this respect.
He said Pakistani authorities had effectively secured the Afghan border, but it was poorly managed on the other side.
Major General Nawaz added that the border had been completely sealed during the recent presidential election in Afghanistan.
He said that it was surprising that Pakistan had 260 check posts on the border whereas the Afghan side had only 40.
The Dawn quoted him as saying that despite poor security measures on their side, the Afghan government continues to blame Pakistan for the infiltration of Taliban.
